Abstract
BACKGROUND Health care quality problems are reflected in the underuse, overuse, and misuse of health care services. There is evidence suggesting that the quality of rheumatoid arthritis (RA) patient care is suboptimal, which has spurred the development of a number of systematic quality improvement metrics. OBJECTIVE To investigate a quality process measurement set in a sample of commercially insured RA patients. METHODS Medical, pharmacy, and laboratory claims for members with an RA diagnosis (ICD-9-CM 714.x) during calendar years 2008 through 2012 were extracted from the Optum Clinformatics Data Mart database. Eight process quality measures focused on RA patient response and tolerance to therapy were examined in the claims database. Measures were calculated for individual calendar years from 2009 to 2012, inclusive. RESULTS The majority of adult RA patients received at least 1 prescription for a disease-modifying antirheumatic drug (DMARD) across the 4 measurement years: range = 78.5%-81.6%. Erythrocyte sedimentation rate and C-reactive protein testing were also evident in the majority of the sample, with 67.1%-72.2% of newly diagnosed RA patients receiving baseline testing, and 56.0%-58.7% of existing RA patients receiving annual testing. Among methotrexate users, liver function tests were performed in 74.5%-75.7% of treated patients, serum creatinine tests in 70.1%-72.6% of patients, and complete blood count tests in 74.5%-76.0% of patients. Additionally, most patients initiating a new DMARD had a claim for a baseline serum creatinine test (68.0%-70.3%) and baseline liver function test (69.3%-71.0%). CONCLUSIONS Findings suggest that a majority of RA patients are attaining patient quality process measures, although a considerable proportion of patients (approximately 25%) may be receiving suboptimal care. Further studies are warranted to understand whether attainment of these measures translates into better outcomes.

Statin or nonsteroidal anti-inflammatory drug use is associated with lower erythrocyte sedimentation rate in patients with giant cell arteritis. J Neuroophthalmol 2011; 31:135-8.

Abstract
BACKGROUND Previous studies have found that nonsteroidal anti-inflammatory drugs (NSAIDs) and statins may impact erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) levels in patients. The current study was performed to determine if NSAID or statin use is associated with lower ESR and CRP in patients with biopsy-proven giant cell arteritis (GCA). METHODS A retrospective cross-sectional study was conducted that included 161 patients via chart review. Charts of patients with GCA seen at the University of Iowa Hospitals and Clinics from 1960 to 2008 were reviewed. Inclusion criteria were adequate medication records, serum ESR and/or CRP on record, no prior corticosteroid use, and biopsy-positive GCA. Exclusion criteria were the presence of diseases known to elevate ESR or CRP. Main outcome measures included ESR and CRP values measured while evaluating patients for GCA but prior to receiving treatment. RESULTS Statin nonusers had an ESR of 85.0 mm per hour (interquartile range [IQR] = 60-110 mm per hour) and a CRP of 8.7 mg/dL (IQR = 2.7-16.2 mg/dL). Statin users had an ESR of 57.5 mm per hour (IQR = 35-85) and a CRP of 2.4 mg/dL (IQR = 0.8-15.9 mg/dL). Statin use was associated with a lower ESR (P = 0.005), while there was no significant association with a lower CRP (P = 0.127). NSAID nonusers had an ESR of 98.0 mm per hour (IQR = 64-116) and a CRP of 8.7 mg/dL (IQR = 2.1-16.2 mg/dL). NSAID users had an ESR of 75.0 mm per hour (IQR = 46-98.5 mm per hour) and CRP of 8.0 mg/dL (IQR. = 1.5-16.2 mg/dL). NSAID use was associated with a lower ESR (P = 0.004), but there was no significant association with a lower CRP (P = 0.522). CONCLUSION Statin use and NSAID use were associated with a lower ESR; however, they were not associated with lower CRP values. Clinicians should be aware that statin or NSAID use is associated with lower ESR in patients with GCA, and this test may therefore have lower sensitivity and specificity for recognizing patients with GCA, and CRP may be a superior test to evaluate patients for GCA.

Abstract
First, IL-6 is produced by synovial tissue of patients with rheumatoid arthritis (RA) and is the principal mediator produced by that tissue inducing differentiation of B-lymphocytes into antibody-forming cells. The Leu-1+ subset of B-lymphocytes is induced by IL-6 to secrete rheumatoid factor (IgM with anti-Fc gamma specificity). Second, the main cell types producing IL-6 in cells dissociated from RA synovial tissue are mononuclear leukocytes. Connective tissue type cells (synoviocytes) cultured from RA synovial tissue produce IL-6 in response to IL-1 beta, and IL-6 formation is increased by TGF-beta. Glucocorticoids strongly inhibit and PGE2 slightly inhibits IL-1-induced IL-6 mRNA expression in synoviocytes. Production of IL-6 increases when undissociated RA synovial tissue is maintained in culture, thus suggesting release from inhibition by a factor or factors not yet identified. Third, the major known local effect of IL-6 in RA synovial tissue is the augmentation of antibody formation and the major known systemic effect is the induction of the synthesis by the liver of acute-phase proteins, especially C-reactive protein. Levels of circulating C-reactive protein are reported to decrease in RA patients receiving long-acting antirheumatic drugs, which would be consistent with the interpretation that immature monocyte-derived macrophages are major producers of IL-6 in these patients.

Abstract
OBJECTIVE Trials of disease-modifying anti-rheumatic drugs (DMARDs) enrol active rheumatoid arthritis patients identified using standard criteria (three out of four of: >/=6 tender joints, >/=6 swollen joints, ESR >/= 28 mm/h, >/=45 min morning stiffness). Concern has been expressed about generalizability, as many patients in routine practice have less active disease. Furthermore, these criteria do not map onto standard disease activity and treatment response measures. We examined how many routine patients were sufficiently active to meet trial recruitment criteria and whether alternative definitions of active disease were more appropriate. METHODS We studied 504 patients in a cross-sectional study, 156 in a longitudinal study and 94 starting new DMARDs or biologics. Patients were classified as 'trial active' (met entry criteria), in remission or 'intermediately active' (between the two). We also evaluated the effect of amendments to criteria. RESULTS Cross-sectionally only 38% patients were 'trial active', but longitudinally 68% were 'trial active' at least once. Thus, many clinic patients do have disease activity below the level required for trial entry, but over time most reach eligibility levels. More (62%) of the cohort starting new treatment were 'trial active', suggesting that recruitment criteria relate to clinical decisions. Criteria omitting morning stiffness and a disease activity score (DAS28) >/=5.4 replicated the classification given by current criteria. CONCLUSIONS Trial results can be generalized to routine practice because most clinic patients are 'trial active' when their therapy is changed and most become 'trial active' over time. As DAS-based criteria are simpler and relate directly to response measures, their use should be considered in future.

Abstract
Ten clinical and three laboratory outcomes were evaluated in 86 patients completing a double-blind placebo-controlled trial of methotrexate in rheumatoid arthritis. The improvement in all measured outcomes was statistically significantly better in patients receiving methotrexate than in patients receiving placebo. The correlations of the changes in outcome measures were calculated to determine if improvement in one parameter was associated with improvement in other clinical parameters. Associations between different clinical outcomes were often statistically significant. Associations between laboratory outcomes were also often statistically significant. However, the association between clinical outcomes and laboratory outcomes was generally poor.

Abstract
The levels of serum C-reactive protein (CRP) were found to be significantly higher in the presence than in the absence of secondary Sjögren's syndrome in patients with rheumatoid arthritis, while the values of erythrocyte sedimentation rate and serum fibrinogen were not significantly different. The levels of CRP were found to be normal in 22 out of 24 patients with primary Sjögren's syndrome.

Abstract
We evaluated the diagnostic value of measuring C-Reactive Protein (CRP) in blood and in synovial fluid for the detection of inflammatory articular diseases in 154 patients. High concentrations of CRP in blood were found in microcrystalin arthritis, polymyalgia rheumatica and Horton's disease. Our results show a good correlation between CRP and erythrocyte sedimentation rate for ankylosing spondylitis (p less than 0.01), systemic lupus erythematosus (p less than 0.01), rheumatoid arthritis (p less than 0.05), polymyalgia rheumatica and Horton's disease (p less than 0.05). The CRP measurement in blood did not separate seropositive versus seronegative rheumatoid arthritis, systemic lupus erythematosus versus rheumatoid arthritis and treated versus non-treated rheumatoid arthritis. There was a good correlation between CRP concentration in blood and in synovial fluid but the concentration was lower in synovial fluid than in blood (p less than 0.01). Then, the CRP measurement in synovial fluid does not have a higher diagnostic value than in blood.

Abstract
Although several agents (for example, intramuscularly administered gold, auranofin, D-penicillamine, hydroxychloroquine, and methotrexate) are of clinical benefit in the management of rheumatoid arthritis (RA), their effect on the long-term outcome of the disease is controversial. Assessment of the influence of therapeutic interventions in RA is difficult because the natural history of the disease remains poorly defined and unpredictable, and neither the traditional clinical and laboratory measurements of inflammation nor radiographic analyses of progression of joint destruction provide an accurate estimate of the long-term outcome of RA. Furthermore, there is little evidence that second-line agents yield benefits beyond 3 years. Therefore, adequately tested comprehensive measures should be used in large, long-term, multicenter controlled clinical trials to determine whether the long-term outcome of RA can be altered.

Abstract
Seventy-one individuals with rheumatoid arthritis (RA) were examined and compared with 52 individuals without history or symptoms of joint disease (C group) with regard to disorders of the stomatognathic system. Laboratory findings and articular and functional rheumatologic indices were compared. The clinical dysfunction index of Helkimo for the stomatognathic system was positively correlated to both the articular Ritchie index and the functional Lee index. The concentration of C-reactive protein (CRP) and the Ritchie index were positively correlated to temporomandibular joint (TMJ) pain. Vertical overbite was negatively correlated to the Ritchie index. In addition, there were positive correlations among TMJ crepitus, anterior open bite, sagittal distance between retruded position and intercuspal position, and erythrocyte sedimentation rate (ESR). The concentration of CRP, the ESR, and the Ritchie and Lee indices were highest in the individuals with bilateral current TMJ symptoms and lowest in those with previous but not current TMJ symptoms. It was concluded that the severity of TMJ involvement in RA is correlated to concentration of serum acute-phase reactants and to rheumatologic indices.

Abstract
A number of laboratory variables, including Hb., ESR and several phase proteins, fluctuated in concord with the clinical signs of synovitis activity in patients with rheumatoid arthritis during a controlled study of 3 disease-modifying anti-rheumatic drugs (DMARD). The correlation between laboratory variables and clinical synovitis was significant in a large patient population but the correlation coefficients were not of such magnitude that any of the laboratory variables reflected clinical synovitis activity in a reliable manner in the individual patients. In patients treated with azathioprine, the response of the Hb, (and consequently of the ESR), was reduced compared to patients given other DMARD. This phenomenon was caused by the bone marrow suppressing effect of azathioprine. However, the effect of azathioprine on the clinical synovitis activity did not differ from that of the 2 other drugs. Similar results were found by reviewing the literature about controlled trials of DMARD. In the present trial the clinical evaluation was performed under optimal conditions. In daily clinical practice the evaluations of the joints may be less than optimal since they may be performed by different rheumatologists with varying experience. Consequently, it may be difficult to do without the unreliable laboratory variables mentioned in the routine assessments of disease activity, unless the quality of routine evaluations of synovitis activity is improved considerably.

Abstract
Life-table analysis was applied to the records of 317 patients with rheumatoid arthritis (RA) treated with sulphasalazine (SAS), 201 treated with sodium aurothiomalate (gold), and 163 with penicillamine. They comprised all those treated in our department with these drugs between January 1973 and July 1984. Risks of treatment termination for all reasons were similar for each drug at five years (gold 92%, penicillamine 83%, SAS 81%). The risk of treatment termination due to inefficacy was less for gold (29.5%) than for penicillamine (38.1%) or sulphasalazine (41.2%). Adverse effects, however, led to withdrawal of gold in 57%, penicillamine in 41.2%, and SAS in 37%; the most effective drugs appeared most toxic. Serious adverse effects were much more common in association with gold (17.4%) and penicillamine (12.3%) than with SAS (1.6%). Sulphasalazine appears as well tolerated over long periods in RA as gold or penicillamine and is associated with fewer serious adverse effects; of these drugs, it might therefore be considered the agent of first choice.

Abstract
Disease activity in 31 children with JRA and 12 with JSA was investigated clinically and by serial measurements of serum CRP and ESR over a one-year period. Prior mean duration of disease was 4.3 years. There was a significant correlation of CRP with ESR and both parameters correlated significantly with clinical disease activity. CRP concentrations and ESR in active disease were significantly higher than in moderately active and inactive disease, though neither parameter showed any significant difference between moderately active and inactive disease. Clinical scoring was more sensitive in detection of moderate disease activity than were CRP and ESR. However, in systemic JRA without articular involvement, laboratory parameters were more useful for assessing disease activity.
